PRINT HEAD ALIGNMENT
Print head position has a direct impact on print quality. The print head must be parallel with the platen roller for the
printed image to be consistent across the label.
1 Ensure the print head is latched.
2 Look downward to print head (1, Figure 6-7) to locate head alignment plate (2).
3 Ensure the values of alignment scales (A) and (B) are the same.
4 Determine which end of alignment plate (2) should be adjusted and loosen its relative set screw (5) or (6).
5 Adjust alignment plate (2) then retighten relative set screw (5, 6) while maintaining plate (2) position.
6 Test print a label to determine if print head (2) is properly aligned.
7 Repeat this procedure until proper alignment is achieved.

NOTE: If the scale values are not the same, this may be the cause of print quality
issues. However, matching scale values does not ensure proper alignment. If the
scales do not match, follow this procedure to align the scales, reprint, and then
readjust as deemed necessary.
NOTE: There is an adjustment aperture (C, D) in alignment plate (2) where an object
may be inserted to assist in adjustment. An appropriately sized Standard screwdriver
works best.
